2. Q factor - Wikipedia

   en.wikipedia.org/wiki/Q_factor

   The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...

3. Sun Television and Appliances - Wikipedia

   en.wikipedia.org/wiki/Sun_Television_and_Appliances

   Sun Television and Appliances was a speciality retailer of consumer electronics, home appliances, and office equipment founded in 1949 by brothers Macy and Herbie Block. The company had stores in cities throughout the midwest, and also operated stores in rural areas of the United States, where there was no other competition [1] in Ohio, Indiana, New York, Pennsylvania, Maryland, West Virginia ...

4. Inductor - Wikipedia

   en.wikipedia.org/wiki/Inductor

   The higher the Q factor of the inductor, the closer it approaches the behavior of an ideal inductor. High Q inductors are used with capacitors to make resonant circuits in radio transmitters and receivers. The higher the Q is, the narrower the bandwidth of the resonant circuit. The Q factor of an inductor is defined as

5. Electrical resonance - Wikipedia

   en.wikipedia.org/wiki/Electrical_resonance

   The quality of the resonance (how long it will ring when excited) is determined by its Q factor, which is a function of resistance: =. An idealized, lossless LC circuit has infinite Q , but all actual circuits have some resistance and finite Q , and are usually approximated more realistically by an RLC circuit .

6. Capacitor - Wikipedia

   en.wikipedia.org/wiki/Capacitor

   In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser , [ 1 ] a term still encountered in a few compound names, such as the condenser microphone .

7. Q value - Wikipedia

   en.wikipedia.org/wiki/Q_value

   Q factor (bicycles), the width between where a bicycle's pedals attach to the cranks; q-value (statistics), the minimum false discovery rate at which the test may be called significant; Q value (nuclear science), a difference of energies of parent and daughter nuclides; Q Score, in marketing, a way to measure the familiarity of an item
